Good news. you don't need to RMA your board. its perfectly fine.
I just switched my 4 dimms of ram from the red slots to the black slots and my board throw error code 65 for me.
so if you only have 4 dimms of ram then you have to put them in the red slots.

Okay then. I thought it was like free to put them in either color slots. But I guess not... I put 1 stick in a red slot, and 4 sticks in the black slots, and it posted fine... So I guess I'm fine. Glad I didn't request an RMA.

Now I just need to get all 8 dimms running, and at 2133... But I've been here for too long. I need to take a quick break from messing with the PC.

hahaha ok

anyways here what you should do cuz maybe I'll not be here.

test all 8 dimms at 2000MHz @ 11-12-11-24 @ 1.6V and keep your VCCSA to 1.2V and PTT to 1.2V.

if it work fine try @ 2133 @ 11-12-11-24.

if you want to go even higher (but i doubt it will go any higher than 2133MHz cuz u hv 8 dimms of ram) try 2400MHz @ 12-12-12-28 @ 1.62V

if it works at 2400MHz then try first to lower your timing. try 11-12-11-28 then 11-11-11-28 etc.. and keep doing that till you find the best timing.

then try to lower your VCCSA from 1.2V to 1.18V and so on. if it still stable try to lower your VTT to 1.18 and so on. if all of this still stable try to lower your Vcore to 1.30V then 1.28V and so on.

FYI max voltage on Air for VTT and VCCSA is 1.2V so don't go beyond 1.2V. Max voltage for PLL is 1.85V on air. and Vcore is 1.4V on air.

The H100 is okay.
Ive had my 3930k up to 4.7 ghz while folding and it gets about low 70s. ( I have push pull with AP 15s)
Ive had the vcore temp nudge 80c a few times but its getting into Summer here, so ive lowered to 4.5 Ghz.
Im confused.. are we talking about Ivy or SB-E? I was under the impression a 3930k was SB-E. Everything Ive read and seen says TJ max is 90c for SB-E

We are talking about the Intel 3930k. I don't know why he posted that link to the Ivy Bridge tests...
